I found this naked foraminifer in material scratched from submerged rocks at the base of the northern dike of Gooimeer (Lake Gooi), the Netherlands, May 2020 (52°18’17.7″N 5°18’51.6″E). The material was kept in some Petri dishes. The cell body was hidden by debris and only once the whole cell was naked and stretched out on the bottom of the dish. Unfortunately, when within soem minutes the cell flowed back to the debris and was hidden again. Only some long strains of granuloreticulopodia were visible. I’m not sure whether this is a Reticulomyxa spec. or another freshwater foraminifer.
